Yes as long as your device is eligible for a Mint eSIM. Currently only iPhone XS, XS Max, XR, any iPhone 11, any iPhone 12, or the latest iPhone SE are eligible, and they must be unlocked.
To get a replacement eSIM, log into the Mint app, head to Settings > SIM > Replacement SIM.
We give you the first eSIM free of charge. If you ever want to switch back to a physical SIM at any time no problem. Just order a Replacement SIM through account management.
